While walking around the Xixi National Wetland Park, I found there were tens of thousands of people, young and old, ______ for the flower festival. Beautiful indeed!

I like to_______ alone about the town after supper.

The rich only _________ themselves in making money and had no eye for the needs and welfare of their workers．

The poisonous atmosphere will surely ______a lot of people.

--- When will your school _______ for the summer holiday? --- At the end of this month.
